He thereforehow makes a new {)nistake by subtracting the' next few numers. I a The. main object of my invention is to fauto'matically bringback the handle from ts correctlng subtracting position to its normal adding position.

The invention is illustrated by the accompanying drawings of which- Figure 1' represents a front elevation of.

illustrate their construction.

For the purpose of explanation of this invention, it is suflicient to point out that'l represents the framework of the typewriter and calculating machine 2, the master wheel; 3,.the totalizer'; 4, the wheels there- .O'f; 5., thc handle which is normallykept in'itsposition' t'otthe right;-adjacent to the extension 6, marked Add, and which has a- .,finger piece 7 by 'means ofwhich itis n1oved,.andmay be shifted by the operatoragainst the forceof th spring 8 out of its previous adding position into its subtractmg position, adjacent to the extension 9' marked Sub (short for subtraction). The mechanism connecting the. handle, the

described in the above cited patent and will not be further explained here.

'master wheel, the keys, etc., 'is thoroughly ator pushes the finger piece 7 of the handle 5 to the left, thereby bringing it from its adding to its subtracting'position, then the pawl 13 under theinfluence of'its spring 14 i.

moves in behind said handle as shown in the-figures, and prevents the same from returning under the influence of its. spring 8. The lever 11 is prevented from being pulled too far down by the extension 15 upon it 5 striking against the top of the handle 5'.

Should the lever 11 now be moved against the force of 1ts spring 14, then its pawl 13 becomes disengaged from the handle 5 which thus becomes free to return to its addingf'position under the influence of its spring 8.

During theoperation of the calculating machine, asexplained in Patent No. 893,719,

the totalizer wheels pass over and engage with the master wheel. As the numbers on this machine are written in the ordinary manner, that is, the highest decimal figures firstand thelowest decimal figures last, the act of writing the units figure shows that the number has beenfinished, and therefore L immediately after the writing of the units figure of the number, the handle should be released from its correcting position to bring it back to its previous adding position. Of

course the carriage of the typewriter andthe totalizer advance one step after the writing of the units figure of a number in the same manner'as they advance after the writing of any other figure. Advantage has been taken of this fact to make this particular step of the totali'zer automatically release pawl 13 previously described, and this is accom- )lished in the following manner.

Attached to the totaliz'er 3 is an extension 20, and forming one piece with the lever, 11

-is an arm 21 formed at its-end into a beveled projection 22, and the parts are so shaped that the projection 20 upon the totalizer comes into contact wit-h the bevel 22 of lever 11 when'the master wheel is immediately to the right of the units totalizer Wheel. The projection 20 in passing by depresses the bevel 22, therefore moving the lever 11, withdrawing the pawl 13 from the handle 5 which thereupon resumes its normal position. Thus immediately after the insertion of the last figure of the correcting number, the mechanism automatically re turns to its adding position.

In the application Serial No. 629,308 filed by John G. WVahl, May 31, 1911, there is shown a handle which normally, occupies one the operation of the calculating machine 18 reversed. That is, it will now add if it'was previously subtracting, or will now subtract if itwas previously adding. The function of the handle of'that application is similar but more general than the function of the handle of this application. Handle 5, as said above, causes addition while in one position, and causes subtraction while in the other position, a change of position therefore causing a reversing in the machine.

Thefunction of the handle of the-other application is similar in that it, too, causes a reversing in the machine; due to the change of position in the handle. t is therefore quite evident that the rest of this application, namely, the paw'liiig of the handle in its reversing'position and the unlocking 'of thefpawl by means of the totalizer or carriage position applies equally well to both.

It is evidentthat the extension 20 upon the totalizer need not be fastened to the t0- talizer directly but might be fastened to the carriage itself. The advantage gained by fastening it to the totalizer directly is that the totalizer may easily be adjusted upon the carriage without needing any special adjustment for the extension, 20, which by .this construction becomes simultaneously auto-' matically adjusted.

The mechanism has here been described in connection with the Remington typewriter in which the paper moves While the type basket is stationary. It is perfectly evident that my invention may be applied with equal ease to other forms of'typewriter. and calculating machines, for instance, calculating machmes mounted upon a book typewriter like the Elliott-Fisher machine. In the latter, the paper is stationary, and it is the type basket that moves. It is thus seen that the movin part of the machine which is commonly caled the carriage may sometimes be a paper-supporting portion, or

sometimes a type-bearing portion. But in every calculating machine wherein the figures of a number are inserted successively, it will be found that there is somemoving portion which determines the decimal place of calculation, and it is to that moving portion that I wish the word carriage to be applied in the appended claims. This carriage may be one piece or composed of several pieces which move in unison with each other but do not necessarily have the same movement. As long as the part moves, and the place of calculation can be determined from the location of that part, the said moving part constitutes the carriage in the sense in which the word is employed in the claims. In'themachine described inthe drawings, the carriage might be the carriage of the typewriter, or might be the bar supporting the totalizer, or in a more limited sense it might be the totalizer itself, or in a still more limited sense itmight be" the extension 20 forming art of the totalizer.

It is evi ent that the mechanism could easily be varied without departing from the spirit of my invention. Forinstance, the spring being taken by gravity. Agaimthe pawl might be eliminated, and in its stead there might be placed a'differently formed piece for 6 and 9 with a notch in it, which notch l l'could easily be removed, its place would serve to retain the handle 5 in its correcting position, until released therefrom.
